RAIL-CLAMP WHEEL-STOP.

Specification of Letters Patent.

Patented May 12, 1914.

Application filed December 16, 1912, Serial No. 737,027. Renewed November 8, 1913. Serial No. 799,993.

To all whom it may concern.

Be it known that I, THOMAS OLIVER, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Rail-Clamp Wheel-Stops, of which the following is the specification.

My invention relates to improvements in rail clamp wheel stops, and the object of the invention is to devise a simple form of stop, which may be adjustably secured in any position on the ball of the rail and it consists essentially of two opposing members meeting over the center of the ball of the rail and extending upwardly therefrom and having hooked lower ends extending around each side of the ball of the rail so as to bear against each side of the rail web and having alined orifices extending through the vertical portion thereof a headed pin extending through such orifices having a key slot in the opposite end thereof, and a wedge key inserted in the slot so as to bear against the adjacent vertical member as hereinafter more particularly explained by the following specification.

Figure 1, is a general perspective view of my device as applied to a rail. Fig. 2, is a side elevation showing a wheel in position against the stop. Fig. 3, is a detail of one of the stop members and headed pin partially inserted in the orifice thereof. Fig. 4, is a perspective detail of the opposing member. Fig. 5, is a detail of the securing ke in the drawings like letters of reference indicate corresponding parts in each figure.

A is a portion of a rail and A is a car wheel supported thereon.

B is my stop comprising the vertical opposing members B and B and hook portions B extending around the ball A of the rail A, so that the vertical portions B and B meet and extend vertically over the center of the rail.

B and B are alined orifices extending through the vertical portions of the members B and B in proximity to the hook ends thereof.

B is a pin extending through the orifices B and B having a head 13 which when the pin is in position, bears against the outer face of the vertical portion B. The vertical portion B is preferably provided with a boss B through which the orifice B extends. The opposite end of the pin B is provided with a horizontal orifice B".

B is a locking wedge key extending through the orifice B and wedging against the outer face of the boss B so as to draw the pin B tight into position and the members B and B together, so that the hooked portions B grip the ball of the rail.

It will be understood that my stop is particularly adapted for light work such as the dumping cars of a dredge where a simple form of stop is required which is readily adjustable to the required position to stop the cars at any particular point.

What I claim as my invention is:

1. A wheel chock, for railway rails, including complemental clamp-members having lower rail-engaging ends and upstanding portions, one of said upstanding portions having a lateral ofi'set or boss, said upstanding portions having coincident passages therethrough, said lateral offset or boss being provided with a passage in continuation of the aforesaid passages, a headed pin inserted within said passages, including the passage-continuation of the boss or offset, and means for the retention of said headed pin in locked position in said upstanding members.

2. A wheel chock for railway rails, including complemental clamp members having lower rail-engaging ends and upstanding portions, one of said upstanding portions having a lateral oii'set or boss said upstanding portions having coincident passages therethrough, said lateral boss or offset being provided with a passage in con tinuation of the aforesaid passages, a headed and slotted pin insertible within said passages including the passage continuation of said boss or offset, and a wedge shaped key insertible through the slot in said pin.
